BCMR retrieve the data from CM at fixed interval.
The default refresh rate for Real-Time Graphs update as fast as every ten seconds. Real-Time Pie Charts update as fast as every ten seconds.
10 seconds is the ideal refresh rate which can be seen when BCMRD is running in Simulation mode or even where BCMRD server and client are running on the same machine), but in practical this will vary from 10 seconds to more seconds depending on the data BCMRD is fetching and the network speed.
This refresh rate will also affect in scenarios where the BCMRD client and BCMRD server are installed on different machines (remote server/client scenario).
